Etymology: Erythrose is a chemist's name built from two pieces. The first, "erythro-", comes from Greek "erythros", meaning red, the same root that gives English words like erythema, a reddening of the skin. The second, "-ose", is the suffix chemists attach to names of sugars, and it is the same ending found in glucose and fructose. The name describes a laboratory result rather than the sugar's appearance. Under basic conditions, the compound turns red, and chemists named it for that colour change. The word therefore records a reaction observed at the bench, not a property of the molecule in its natural state.

Synonyms: tetrose sugar
